Google App Engine Python SDK os module privilege escalation
|google-apps-osmodule-priv-esc (71062)||High Risk|
Google App Engine Python SDK could allow a local attacker to gain elevated privileges on the system, caused by the failure to prevent use of the os module by the sandbox environment. An attacker could exploit this vulnerability using a file_blob_storage.os reference within the code parameter to bypass security restrictions and execute arbitrary commands on the system with elevated privileges.
Upgrade to the latest version of Google App Engine (1.5.4 or later), available from the Google Apps Web site. See References.

- CVE-2011-4213: The sandbox environment in the Google App Engine Python SDK before 1.5.4 does not properly prevent use of the os module, which allows local users to bypass intended access restrictions and execute arbitrary commands via a file_blob_storage.os reference within the code parameter to _ah/admin/interactive/execute, a different vulnerability than CVE-2011-1364.
